"Trauma" takes place in the dreams of a girl burdened with trauma. As her cherished koala doll, you will explore a surreal world and exorcise nightmares! This game is created with respect to numerous classic walking simulators, featuring ever-changing fields that transform to keep the gameplay engaging. The only action players can perform, other than walking, is stabbing with a knife, which serves as a metaphor for overcoming trauma and is the key to completing the game. Horror elements are generously incorporated, providing a proper dose of tension. The dark and melancholic atmosphere builds a unique world, offering both terror and solace to the player. Enjoy this bizarre dream world, accompanied by newly composed ambient BGM crafted specifically for this game. The number of endings is one.
